Definitions
- the invention relates to a heat exchanger for a motor vehicle, in particular a coolant / air cooler according to the preamble of claim 1.
- Heat exchangers for motor vehicles such as coolant / air cooler, charge air / air cooler, Refrigerant / air condensers and / or oil / air coolers are usually arranged in the front engine compartment of the motor vehicle, wherein said heat exchanger often to a pre-assembled Cooling module are summarized.
- Such cooling module consisting of a coolant / air cooler, a Charge air / air cooler and a refrigerant / air condenser known.
- the Heat exchangers are firmly interconnected to form a structural unit, which is inserted into the vehicle and fastened there. For the attachment has one of the heat exchanger fastening elements z. B.
- the different Fastening elements through the use of so-called exchangeable inserts produced on the injection mold.
- the injection mold for spraying of the collecting tank comes with different interchangeable inserts, the especially to the different dimensions and positions of the fasteners are fitted, equipped so that the rest of the tool the same remains.
- the fasteners formed as a holder with an L-profile, with a (vertical) L-leg is integrated into the wall of the collecting tank and the other (horizontal) L-leg protrudes from the collection box and a foot for the Attachment of the heat exchanger forms.
- This foot has different Lengths, depending on installation requirements in the vehicle. This will be the Advantage achieved that the heat exchanger -. B. in the direction of travel Vehicle seen - in different positions, eg. B. 5 cm further fastened at the front with the same vehicle-fixed attachment points can.
- the L-legs stiffened by ribs, so that in cross section a U-profile with increased Resistance moment results.
- the ribbed L-profile is suitable in particular for receiving bending stresses, which in the prolonged foot increasingly occur.
- the upper fastening elements formed at the collecting boxes as open box sections, which can be sprayed on at different positions of the collecting tank are, for. B. on the front and on the back. This happens as well by replacing the inserts in the injection mold.
- upper fasteners is the heat exchanger or the cooling module attached to the upper cross member of the vehicle by there vehicle-mounted Engage mounting pins in the box profiles.
- the heat exchanger is used with the fasteners as a carrier for other heat exchangers such as B. a charge air cooler and / or a refrigerant condenser, as seen in the direction of air flow, in front of or behind the heat exchanger, which is formed in this case as a coolant air cooler, arranged are.
- the coolant air cooler is used with the fastening elements according to the invention as a carrier for the entire cooling module.
- Fig. 1, 1a, 1b and 1 show in different views, a cooling module 1, which is composed of a coolant radiator 2, a charge air cooler 3 and arranged between the two refrigerant condenser 4.
- the heat exchangers 2, 3, 4 are mechanically connected to each other in an unspecified manner here to form an assembly, the cooling module 1.
- the coolant cooler 2, which acts as a carrier for the entire cooling module 1, has a network (block) 5 soldered from flat tubes and corrugated ribs, not shown, and two laterally arranged collecting boxes 6, 7 made of plastic, each of which is mechanically connected to a metallic tubesheet 8, 9 are connected.
- the coolant radiator 2 is designed as a so-called cross-flow radiator, ie installed with horizontal pipes and vertical collecting tanks 6, 7 in the vehicle, not shown.
- the collecting tanks 6, 7 each have a coolant outlet nozzle 6a and a coolant inlet nozzle 7a, via which the connection to a coolant circuit (not shown) takes place.
- the intercooler 3, the charge air pipe 3a, 3b has, connected to an unillustrated charge air system and the refrigerant condenser 4 via a connecting flange 4a with a refrigerant circuit, not shown, of a vehicle air conditioning.
- the cooling module 1 is flowed through by ambient air in the direction of the arrows L.
- the support of the cooling module 1 via lower fasteners 10, 11 and upper fastening elements 12, 13 (FIG. 1 a), which in each case the coolant boxes 6, 7 are molded, d. H. integral with these in Plastic are formed.
- the lower fastening elements 10, 11 are designed as L-profiles and have on their underside each have a mounting pin 10a, 11a, by means of which the cooling module 1 in not shown elastic receiving bushes on a cross member, not shown of the vehicle is fixed.
- the distance, seen in the direction of travel, between the mounting pins 10a, 11a and the end face of the radiator network 5 is indicated by L1.
- the upper fastening elements 12, 13 are formed as open box sections, which on an unillustrated upper lock cross member of the vehicle are held.
- Fig. 2a and 2b show two different perspective views of the coolant radiator 2 of FIG. 1, seen in the direction of travel, ie in the direction of the air outlet side of the network 5 and the open sides of the coolant pipe 6a, 7a and the charge air nozzle 3a, 3b.
- the fastening element 11 is molded in the form of an L-profile, ie in the form of a horizontally projecting foot which is stiffened by two lateral ribs 11 b, 11 c.
- the fastening element 10 likewise molded in the form of an L-profile, is injection-molded on the coolant box 7, wherein a horizontally protruding foot with stiffening ribs 10b, 10c can also be seen here.
- the fastening pins 10a, 11a are injection-molded, which serve to receive horizontal thrust forces.
- the upwardly open box section 12, 13 are arranged.
- FIG. 3a, 3b and 3c show different views, namely from the front, from above, from below and from the side of a second type of cooling module 1 ', which differs from the previously described cooling module 1 only by the dimensions and the positions of Fasteners 10 ', 11' 12 ', 13' different.
- this cooling module 1 ' corresponds in terms of number, size and design of the heat exchanger, the cooling module 1.
- L2 the distance of the mounting pins 10a', 11a 'of the end face 5' of the coolant radiator 2 denoted by L2.
- L2 is considerably larger than L1.
- the ratio L2 / L1 which results here from the graphic representation, however, is arbitrary and can vary up or down, z. B. by lengthening or shortening of the foot 10 ', 11'.
- the further views Fig. 3a and Fig. 3c also show the enlarged dimension L2 compared to the first embodiment of the cooling module 1.
- the upper attachment points are offset, ie the fasteners 12 ', 13' are located in the cooling module 1 'and at the coolant cooler 2 'on the back of the coolant boxes 6', 7 ', ie on the side of the air outlet surface 5'.
- the direction of flow of the air through the cooling module 1 ' is indicated by arrows L (the direction of travel, not shown, of the motor vehicle is the opposite direction).
- FIGS. 4a and 4b show two different perspective views of the coolant cooler 2 'with a view of its air outlet-side end face 5'.
- the perspective representation shows the different lengths of the feet or fastening elements 10 ', 11' in comparison to FIGS. 2a and 2b.
- the different positions of the upper fastening elements 12 'and 13' which are arranged here on the back of the coolant boxes 6 ', 7'. They are offset from the first type of cooling module 1 by approximately the same amount in the direction of air flow as the fastening pins 10a ', 11a'.
- the change in the dimensions of the lower fasteners of L1 to L2 and the change in the positions of the upper fasteners 12 ', 13' from the front to the back causes the installation of the cooling module that the cooling module 1 'by the difference L2 - L1 in the direction of travel in the vehicle moves forward - as already mentioned, at the same Attachment points in the vehicle, d. H. in the lower and upper cross member.
